SecondBrain is a voice-first memory app that remembers everything for you, so nothing slips away.

Just open the app and talk. Speak an idea, a task, a name, a moment you want to keep, and SecondBrain turns it into a clean, organized note on its own. No typing, no folders to manage, no system to maintain. The AI structures everything into a clear tree that grows into a living map of what you know and what you have been thinking about. Your own secon dbrain, built one voice note at a time.

It also connects to your calendar, so the things you capture can turn into the things you actually do.

The part that makes SecondBrain different: it plugs into the AI tools you already use. Connect Claude, Gemini, and GPT, and they all share the same memory. Tell SecondBrain something once, and every assistant you work with can recall it (and the other way around). One memory, everywhere you think.

Built for anyone whose ideas move faster than they can write them down.
